f f Application led November. 1912. Serial No. 730,222.

To all whom it may concern.'

Be it known that I, HARRY M. PFLAGER, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in Car End Frames, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l. is an elevational view of a car end frame of my improved construction. Fig. 2 is a side elevation of the end frame. Fig; 3 is a vertical section taken on the line 3-3 of Fig. 1. Fig. 4 is a vertical section taken approximately on the line 4-4 of Fig. 1. Fig. 5 is a horizontal section taken approximately on the lineof Fig. 1.

This invention relates generally to railway car construction, and more particularly to the one-piece cast metal end frames for cars of the type disclosed in Patent No. 917,716, issued April 6, 1909, and No. 929,705, issued to me August 3, 1909.

)ne of the most important features in the construction of the present typesy of railway cars, and particularly those utilized 'for the transportation of passengers is the reinforcing of the ends of the cars so as to provide an exceptionally strong, rigid construction which will effectually resist crushing stresses delivered to the ends of the cars, consequently overcoming the tendency of the cars to telescope in case of collisions, and affording the .greatest possible degree of safety to the occupants of the cars.

My improvement contemplates a comparatively light-weight, strong and durable one-piece, cast metal structure, formed, braced and connected to the car underframe and superstructure so as to combine therewith in resisting end shocks and crushing stresses imparted to the-end of the car, thereby providing a construction which is anti-telescopic in effect.

The principal objects of my present invention are, to generally improve the construction of one-piece end frame of the type disclosed in the patents hereinbefore referred to, and to construct an end frame having a centrally arranged door openingand pair of comparatively large window openings on each side of said door opening,

which arrangement is particularly desirable f or use on passenger cars having observation ends.

To the above purposes my invention consists in certain novel features of construc- .tlon and arrangement of. parts hereinafter lnore fully described rand claimed.

Referring by numerals to the accompany- Aing drawings A designates the |car underframe and B the end sill, which latter, in lthe present instance, is shown as an integral part of the underframe. f

My improved end frame, as shown, includes a base member 10 that is substantially of inverted L-shape in cross section` said base member being applied to the end sill B with the vertical leg of said base member 10 positioned against the outer Afront face of said end sill and with the horizontal leg or flange positioned on top of said end sill. The legs or anges of the base member 10 are provided with rivet holes which receive rivets utilized in attaching the end frame to the end sill. The vertical leg or liange of this base member is notched or cut awayadjacent to its center, as designated by 11 in order to accommodate parts of the car platform, and to compensate for thus notching said base member strengthening fianges 10 are formed integral with said base member immediately above the notches or cut away portions.

Formed integral with the ends of the base -10 are upright members 12 which perform the function of corner posts for the car body, and the lower portions of these uprights are extended 'rearwardly to form brackets 13 which rest upon and are attached to the side sills of the underframe, and the rear lower ends of said brackets engage against shoullders 14 formed on the underframe. The uprights 12 are fianged and of any desired shape in cross section.

Formed integral with the central portion of the' base 10 1s a pair of flanged uprights 15, preferabl of I-beam shape in cross section, and which uprights perform the functions of door posts.

Formed integral with the upper ends of the uprights 12 and 15 is a horizontally disposed top rail 16, and formed integral with the central portion of this top rail and projecting upwardly therefrom is a skeleton frame 17 adapted to receive and support parts of the upper portion of the car body such as the hood or hood frame, the deck plates, deck sills and roof structure.

Formed integral with the lower portions of the posts 12 and 15 are horizontally disposed rails 18 which constitute window sills, and formed integral with the central portions of said sills and extending downward to the base 10 are vertically disposed rails 19. The members 18 and 19 are flanged and of any desired cross-sectional shape.

Formed integral with the upper portions of the uprights 12 and 15 and below the end portions of the top rails 1G are horizontally disposed flanged rails Q0 which constitute lintels for the window frames.

An end frame of my construction is pref erably cast in a single piece, and such construction does away with much time, labor and consequent expense ordinarily involved in the construction and assembling of a built-up end frame.

An end frame constructed in accordance with my invention is very strong and rigid, can be readily attached to the underframe, and by providing brackets on the lower endsof the corner posts, an exceptionally strong anti-telescoping structure is provided which affords a maximum degree of safety to the occupa is of the car in case of collisions.

T he end frame having a centrally arranged door opening and a pair of comparatively large window openings is especially desirable for use in connection with passenger cars having observation ends.

It will be readily understood that minor changes in the size, form and construction of the various parts of my improved end frame can be made and substituted for those herein shown and described without departing from the spirit of my invention, the scope of which is set forth in the appended claim.

I claim:

The herein described car end frame comprising a flanged base member, a pair of flanged door posts, a pair of flanged corner posts, a flanged top rail uniting the upper ends of the posts, horizontally disposed flanged rails between the upper portions of the door posts and corner posts, which last mentioned rails constitute, lintels, flanged rails between the lower portions of the door posts and corner posts, which last mentioned rails constitute window sills, which arrangement of posts and lintels and sills provides a window opening extending the entire width of the space between each door post and corner post, vertically disposed members betwe'en the central portions of the sill members and the flanged base member, and rearwardly extending brace members extending from the inner lower portions of the corner posts and designed to coperate with shouldered side sills, all oit which parts are formed integral,

In testimony whereof I hereunto alix my signature in the presence of two witnesses, this 22nd, day of October, 1912.
